INTERLOCKING FLOOR AND PANEL.

Specification of Letters Patent.

Patented Aug. 10, 1915.

Application filed June 19,1914. Serial No. 846,037.

To all whom itmay concern:

Be it known that I, AARON VVoLosrIIN, a subject of the Czar of Russia, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Interlocking Floors and Panels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in the j oining of different elements composing sections of interlocking floors and panels and more particularly refers to improvements in the joining of elements composing interlocking floors of the type described and claimed by me in a patent for interlocking floors patented Feb. 25, 1913, No. 1,054,070.

The object of this invention is to provide an improved form of joint for assembling the different elements composing sections of interlocking floors, each comprising two side runners and a plurality of primary base sections and primary upper sections connected to and interlocking with the same, such as described in the above mentioned patent.

In the annexed drawings Figure l is a cross sectional view in elevation of the same floor, modified according to the present invention; and Fig. 2 is a cross sectional detail view in an enlarged scale, illustrating the outline of the groove provided in the runners, modified according to the present invention.

The interlocking floor to which said above mentioned patent refers is composed of group sections each composed of two side runners provided with longitudinal grooves, having the upper and lower face downwardly inclined in substantially the same direction said group sections furthermore comprise primary base sections and primary upper sections each provided with tenons, which when combined together will interlock with said groove. Inthe construction just described, however, in order to assemble each group section it is necessary to insert both primary base and primary upper sections at the end of the runners and to slip them through one by one, until the grip section is completed. The different elements thus assembled are also preferably glued together so that the result is a floor composed of individual group sections, which can be readily laid in place, and each of which is solidly and compactly assembled in a factory under economical industrial conditions. In the manufacture of these floors I have found that their construction can be further improved by modifying the outline of the groove provided in the runners so that the primary base sections can be directly laid in place without the necessity of inserting the same at one end of the group section; by this-a considerable economy in cost of manufacturing is effected, because the time required in assembling each group section is shortened, while the resulting construction is just strong and compact as the one of the floor previously described.

According to my present invention, and referring to the drawings, the grooves pro vided in the runners have a W outline inwardly inclined at substantially 45 degrees. In the preferred form of outline the two intermediate faces of the grooves are at 90 degrees to each other, so that one face remains inahorizontal plane while the other one remains in a vertical plane; and the outline is such that the plane passing by said vertical faces clears the end of the dovetailed tenon formed by the upper face of the groove and by the upper surface of the runner. Referring to said drawings, it is seen that each group section is composed of side runners 20, 21, primary base section 22, and primary upper sections 23. Each runner is provided with a longitudinal groove, having substantially a W outline and comprising an upper inclined face 24:, and horizontal face 25, a vertical face 26, and a lower inclined face 27. Upper inclined face 24: and upper surface 28 of the runner form a dovetailed tenon 29, the end of which does not project beyond a plane passing by face 26 and shown by dotted line A A.

When the runners are laid at the proper distance between each other the primary base sections can be laid in position directly from the top of the space between the two runners, since the same are registering with vertical faces 26 of the grooves, and will therefore clear the end of the tenons 29 as a natural consequence of the construction described. This as stated does away with the necessity of slipping said base section through one end of the group section and therefore eifects a considerable saving in time and cost of manufacture.

In order to reach the desired end, 1t 18 obvious that it is not strictly necessary that at 90 degrees, since the same may be at a somewhat narrower or Wider angle if desired. The resulting construction will still be a floor composed of primary group sections, each comprising side runners interlocking with and retained by a plurality of primary base sections, and interlocking with and retaining a plurality of primary upper sections, and, when all the elements mentioned are assembled together it will still be impossible to separate the same unless the primary upper sections are slid out of their position endwise in reference to the group section.

I claim:

1. In a floor group section, and in combination with a plurality of primary base sections, and a plurality of primary upper sections, runners interlocking therewith having inwardly inclined grooves having substantially a W outline; the ends of the upper V of said W not projecting beyond the apex of the lower V for the purposes as set forth.

2. A floor composed of a plurality of independent group sections, each comprising two side runners provided with a substantially W shaped groove having the two outer sides inclined in about the same direction, the ends of the upper V of said W not projecting beyond the apex of the lower V, a plurality of primary base sections provided with tenons registering with the lower V section of said grooves, and a plurality of primary upper sections provided with tenons registering with the remaining V section of said grooves; substantially as set forth.
